The use of cosmogenic nuclides has revolutionized the quantification of fault motion by filling a critical gap between short-term geodetically recorded slip-rates and geological-long term- slip rates. In this lecture I will present 1-the important aspects to be understood when dealing with cosmogenic nuclides from sampling strategy to getting exposure ages, 2-several applications such as the use of depth profiles to date the emplacement of morphological surfaces, fault scarp dating to unravel past seismic events, relief building and denudation rates, and a novel application on triangular facet to assess normal fault slip-rates.
